Hi,
I have my sgs about 2 months and I'm very happy with it. The only problem I have is, that sometimes there are strange displayinterferences.
It looks like there are moving waves from top to down.
Does anybody have this troubles too and has a solution for it?
Or is it an hardware error? The problem is that the error isn't reproducable.
Maybe somebody can help me, please!
Thanks in advance

I think I have also noticed that once or twice. I believe it can be seen when you have the android drop down menu (notifications etc) open and you start or stop WiFi. It must be some kind of interferance with wifi hardware. Normal wifi operation does not cause it, only the startup of the WiFI which lasts one second or so.
Yeah, i think this could be true. I also see it often, when I open die Notification bar. But I also have the same interferences, when I am working in apps. Maybe also the 3G connection could be the reason? Does anybody else have this problem.
Is this a problem, which I have to life with or could this be an error of the hardware(warranty)?

I have the same problem. Never on wifi tho.
Which firmware are you using?
Hi,
my firmware is I9000AUJF1(A1 branded from Austria). I don't know if the problem in your posted thread is the same. The interferences I mean only exist one or two seconds. There are horizontal dark lines which moves from top to the bottom. After some time everything is OK again. It looks like anything interfers the display(wifi, 3g?).
The problem of warranty is, that I'm not able to show the problem, because it's not reproducable.
Screen flickering under WiFi data transfer
I noticed this problem a couple of days ago.
Whenever there is some data transfer going on over WiFi, wherever I am browsing or some service syncs up the screen starts flickering and I have what I can describe as faint scan lines crossing the screen vertically like there is some sort of interference.
These are mostly noticeable on white and light grey backgrounds.
I have gone trough 2 firmware updates currently being on stock JPK rooted.
I have searched around on google and found on some forum one guy that was saying the cause is an interference between the WiFi module and the screen refresh rate.
Has anybody encountered this problem or these symptoms ?
Is there somebody around more knowledgeable in this issues that can confirm that this is a hardware problem ?
wow! , you might have a defective phone then.
I use WiFi very often, Wireless N at aprox 87 Mbps
that should be high enough to reproduce the problem you experienced, if i had a faulty screen
the description of the scan line reminds me of interference when you are in close proximity with another LCD or CRT screen causing the distortion field
OMG, I get this too. Usually happens on boot or when I'm browsing a data heavy website or using Android market. Are our phone defective? Does anyone else have this problem? I wonder how common it is.
does the scan line comes from bottom up
or goes from top to bottom?
very slowly or fast?
if you are pluged in and charging, also are you in a 120v or 240v?

They tend to be random and I'm on battery power atm. Also they're quite fast but don't last very long. They'll start then stop then start etc ..
Hi,
just for your information. I've sent my phone to samsung on friday. Maybe they find the error. I report, if there are new information.
Yep i have the same problem. Can t find the source though....

The lines appear from top and travel the screen fast.
Imagine a TV who for a second has problem with reception.
I am on 240 V.
Also the issue is much more noticeable when not plugged in.
If I have the phone plugged in its barely noticeable.
I will try to call the service and ask about this issue. I have a strong feeling that this is a hardware issue. But Besides the screen being defective I also think about the battery. Maybe when in high load (WiFi) it's voltage varies and affects the screen.
It seems if I uncheck Power saving mode in Settings>Display and also uncheck Automatic brightness things improve a bit.

Another issue to worry about .. God starting to think about selling this phone and getting something else. Stuck in a 2 year contract though
some one already reported this on another topic
it does seems that some version of the phone are prone to WiFi interferance
we still haven't found out what causes it exactly
for example i can not replicate the issue on my phone when using WiFi
found it
http://forum.xda-developers.com/showthread.php?t=793944
Cant reproduce it.
Not that I'm unhappy with it...
If this is a hardware issue Samsung should replace my phone. I am waiting though a little bit before calling the service to make sure that it is a hardware problem.
If I find that it can easily be fixed with a software fix, it's not worth the hassle of trying to replace it.
can anyone in North America confirm this issue?
i got a huntch it might be an Europe only issue related to the high voltage of the electric interferance nearby, like lights, tv, radio, wifi, etc.
I've scoured the internet in attempt to resolve this issue, and I know it's been talked about many a time before, but this just doesn't have an answer yet afaik.
Does anybody have any experience with fixing the inaccuracy of the touch screen after prolonged use? I love the nexus one, it's by far the best phone I've owned; but this little bug makes the phone completely unrealistic in real-world use.
If this isn't a software issue, it has to be something with the digitizer being powered off and back on to remove the accuracy bug. In that case, is there any low-level way to turn the digitizer off and back on as fast as possible every X seconds? That would mean losing touch capability for a few milliseconds, but is much better than locking and unlocking the phone each time it "goes wild."
I had given up all hope that this issue could be resolved in any fashion as dodgy hardware is, well...dodgy. Nothing can be done about it right?
I haven't had a screen wonk since starting in on the CM7 nightlies many moons ago!
IN YOUR FACE WONK!

No, but it's been covered so extensively that nobody really mentions it any more. Either that or others have found what i have, that somehow the CM7 ROM mitigates the problem. Seriously, i haven't had an issue with it for months!
My particular N1 was never good with stock ROMs. Hated them and gave me endless trouble with one thing or another. It's the polar opposite for me with CM ROMs. Never any issues at all. No call or screen wonk, none of the bugs that others often complain about. It's like the phone has an attitude!
After flashing something ridiculous like 40+ CM7 Nightlies and stable releases, i've not had to wipe data once

Can you please describe what the digitizer issue was/is? I just ordered N1 and haven't received it yet. And what about call wonk? I haven't seen anything about this one.

Basically the digitizer has a couple of quirks. One is that after prolonged use (I found it to be completely random) the accuracy goes berserk, registering touches nowhere near they actually are. Secondly there is a switching of the axis when you cross two points: video. They are hardware related so there is no fix. The wonk is a problem with CyanogenMod7 specifically, causing black screens when receiving calls.
Personally I rarely if ever come across the digitizer problem and have never came across the wonk. They aren't deal breakers but can cause a few problems if you play a lot of multi-touch games.

Well, the touchscreen issue is nothing more than a bad digitizer that was released with the phone and never improved during manufacture of the device. All Nexii have the same one, although people suffered the problem in varying degrees. What would happen is every so often your touch on the screen would register in the wrong place so you may be selecting a shortcut on your homescreen to launch an app, but it might register the touch as being an inch higher/lower/somewhere random. the solution has always been to simply press the power button to turn the screen off/on again. This would fix the issue... until it occurred again.
The call wonk is really in two parts. Stock GB ROMs had a habit of introducing a slight delay in one party being able to hear the other during the start of a call. On CM7 ROMs it was a more significant issue of black screens and freezes during the start of a call. These didn't affect affect everyone though, and even Cyanogen himself didn't have it on on his own device.
EDIT: The other issue affecting the N1 was a weak, and often failing, power button. With the need to keep using it to fix the screen wonk the problem was made worse. That's why you might often see mentions of Trackball wake as it reduced the need to use the power button, therefore extending it's life. Trackball wake is only available on custom ROMs so bear that in mind too!
The phone isn't perfect but with the custom ROM devs doing there thing it's pretty decent for me
Hollow.Droid and DirkGently1 - I appreciate your responses.
Can I bring your attention to my other question to which nobody responded yet?

When the issue happens you just lock and unlock the screen to fix it. No need for a reboot.
This issue isn't really such a big deal. It happens once a week or so, and it takes a few seconds to black out the screen then unlock, problem gone.
My stock Touchpad has a weird color problem. Anytime there is some shading/gradient type effect, red/green/blue hues appear. Solid colors seem fine but when I try to watch something like a movie...every person looks like Obama's HOPE poster. Even the normal grey backgrounds of the UI/Cards look like they are running in some 8bit mode or something.
HP live chat previously ASSURED me it is not a hardware problem but rather a software problem. I have done all the updates/factory reset/etc. Nothing has improved. Has anyone seen this type of problem? Is there a 8bit color switch somewhere? Thanks for reading/any help!
I attached a tiny low res pic of the problem. The problem is pretty obvious
Does it work correctly in WebOS? That would tell us if it is a cm problem or a hardware problem. Boot over to WebOS and try watching a movie. I haven't heard of this being a cm problem.

It doesn't even have CM on it. I'm actually wondering if I flash android on it...it'll get fixed. Will give it a try when I have more time but might just try to call warranty on it. My warranty has passed 1 year but hopefully my credit card company should cover it. I'm thinking I should try that first before wasting time on flashing.
Such a weird problem that has stopped me from using/enjoying my TP
Its hard to even tell what the problem is in your picture. But is your screen discolored in that one spot or is the whole screen discolored? I've never heard of a software issue causing that. And if it was a software issue, running the webOS doctor should have fixed it. So if its still under warranty, i'd go that route first.

The issue is the entire screen. The picture is supposed to be mainly dark grey/grey/white. The blue/green tints pretty much appear wherever there is slight color gradients. Its quite obvious on non-solid colored UI and skin. It looks like basically watching a person while on acid.
Anyone know if its possible to have a faulty GPU or something on it and still boot up? The TP does feel sluggish in other aspects as well...open up just a few cards and it becomes pretty damn sluggish. Doesn't even have to be a web browser card...something simple like calculator can sometimes cause problems...

If its your whole screen, it could be that your screen is messed up. If you have the warranty still, I'd see if you can get it replaced.
hi i am in the uk.. on three network. i got my htc one on the 3rd of april, and 4 days later the screen started to flicker? not all the time? but browsing? esp facebook or anything page with white? i guess the white shows up the flicker more? like i say NOT all the time but soo annoying!! not what i expected from a high end phone? Now let me just say i love this phone.. but thought i cant have this.. so i fill out support form for htc and they reply quick advising me it should not do this and to get it changed. i contact three go through the whole call centre thing (like pulling teeth) anyways the upshot was.. three sent me another brand new phone the next day (yesterday) and took back my first one. And guess what? as soon as i switch the phone on, same screen flicker? i treated the first phone like a new born baby didnt drop or bash it 4 days=screen flicker. another new phone as soon as i use it = screen flicker!! i so love this phone but im so gutted!! any suggestions from ANYONE would help.
kind regards

This isn't helpful but you must just be unlucky to have had it happen twice because mine's been perfect and I've not seen anyone else on this forum mention that problem with theirs.
I guess you'll have to get a new one sent out again and hope for the best :thumbup:

hi.. to be honest i dont think a video would pick the problem up? you know i could just be being a kill joy? ive watched videos etc and there really isnt a problem with that at all.. in fact the quality of the picture is fab? if i could use an analogy? remember when the volume control on your stereo would get dust in it? and you would have to twiddle the knob to cure it? its a bit like that? like i say it does not do it all the time but i notice it with white in the screen? like facebook google and when i am navigating thru the screens on the phone like settings etc? the white flickers white/slightly darker white? hence my example? now ive changed my text messages colour scheme so that doesnt annoy me now with it.. but obviously as a electronics layman.. i cant help but think if it was a problem with the screen itself, other colours would do the same as they would if there was a loose connestion? and also if it was a power flow problem with the battery? same thing? not just the white on screen? so i can only conclude as a layman again.. that it is some sort of issue with the os? screen refresh rate maybe? i just dont know? and i cant help think stupidly or not that when htc finally get around to an os update to 4.2.2 (or whatever it is) from 4.1.2 the whole thing will be resolved?
Could it be the auto brightness doing its thing? Try turning it off maybe that might solve it.
I might be totally wrong, be great if that fixed it though. Good luck
well well well!!!! And there you have it!! or at least something like that? ive always used the multi widgit for wifi bluetooth brightness etc? so i have brightness preset on that. instead ive gone into display settings, adjusted brightness with slider? no more flicker!! NO MORE FLICKER!! who ever you are!! thank you!!!!!!!!!!

Was this happening when the stock power widget brightness was set to medium?
If so, I have the same flickering ( http://forum.xda-developers.com/showthread.php?t=2243483 ), but I've found out that its not the power widgets fault per se, but the the the level that it sets it to. The widget set the brightness to 33%, and that the level which I'm getting flickering at, regardless of if it was set with the power widget or by the slider. The flickering happens on screen with a good amount of white. Google search result webpage is a good test case; it shows the flickering clearly at 33%. It also seems to depend on where the white is on the screen. For example, I can induce flickering at 40% brightness by moving a light colored icon from the bottom of the screen to the top! Moving it back to the bottom causes the flickering to go away. I can also do it by moving around or resizing the Gmail widget. Flickering happens for me to some extent at brightness values between 33 and 45 under certain screen conditions. Above or below these brightness values, the screen is top notch, no endless flickering at all regardless of how much white is on screen. I'm starting to think this has to do with the dynamic contrast feature of the One. It seems as though it falls in an endless loop of trying to change the contrast, as if it cant decide on what to set the contrast to. Or it could be that the dynamic contrast is fighting for a certain brightness value, but the manually set brightness is not allowing it. I might be wrong about this, and it could just be a hardware backlight problem, regardless, I wish HTC had the Sense (ha ha!) to allow us to disable dynamic contrast if we wanted to. I'm pretty sure this is whats causing the issue where people see flickering when the keyboard pops up.
screen issue?
hi..
i had the widget set on the third setting, the fourth being the brightest. i had the same problem with my first phone and thought at the time it may have been a backlight problem? or power flow problem? i sent that phone back and the next phone did the same? after posting on here.. i removed the widget and manually adjusted the brightness. i like the screen quite bright, manual adjustment cleared the problem for me. i gotta say yep the flicker was more visible on screens with alot of white, google, facebook, texts? and way way annoying! i can only suggest you try the same as i did? perhaps it is just a quirk with the htc? or maybe the os? you never know, when the update to keylime or whatever it is called comes out the flicker may go totally?
JUST had this on facebook? hope it helps?

Hello. Issue is the screen all of a sudden turns into very phosphorite colours. I've searched for any similar issue here in xda and have not seen anyone else with this problem..
In another forum (Spanish only) various people have reported the same issue after my post there. And in most of the cases the issue seems to show up after watching a video/movie potentially related with Netflix and/or HDR.
Rebooting solves the issue. And another person reported that after leaving the phone locked for some time the colours were back to normal...
Have note 8 for less than a month and this has happened 2 times already.
I post here as audience will be wider.
Anyone with same issue or idea?
Thx a lot

I think we're waiting on pics. Phosphorite is a rock, so I'm not sure what phosphorite colour means.
sounds some settings in the screen mode were changed. when it happens again, dont reboot just go toggle a few different setting and see if it fixes it. also, having tinted colors(phosphorous?) seems as RGB got changed under the advanced settings in the display mode settings.
I do know some apps are be able to change brightness so mybe other can change color settings? some sort of a blue light filter or 'night' mode?( tint to a warmer shade?)

Is it only when you're charging? I have my screen saver set to colour, and I'd describe those as psychedelic. But I just have to touch the screen to make it stop.
Haha. Yes phosphorite is probably not the right word... the screen turns into fluorescent colours (like in a highlighter pen). Hope this clarifies... let's see if it happens again and I take some pictures.
Thanks for the responses so far
